With the liberalization of the national two-child policy is getting closer and closer, eligible couples are more eager to try, but the joy and have a hidden worry, after all, the years are not forgiving, the body’s function is gradually going downhill, I do not know if their reproductive function is still like before? In fact, pregnancy is a simple but very complex process for every couple. Simply put, if there is a good egg, a good sperm, coupled with a good channel and good soil, the seed will take root, germinate, gestate and grow, go through the October conception, and then go through the pains that are so deeply engrained in your heart that you will never forget them, a new life is born! The whole family is immersed in happiness. But this must have a good premise, that is to have a good egg, a good sperm, plus a good channel, good soil. During the period also have to go through so many complex processes, and by so many factors, such as some of your current basic conditions: age, mind, mood, physical or whether there are still some secondary infertility disease ~ The best age for women to have children is 25-29 years old, the age of preparation for the second child is actually in an awkward age, a few after 70, the vast majority of 80, why talk about the age of it? Because this part of the age of the people more than 35 to 45 years old or so, have missed the optimal age of fertility, in this stage of age of women’s body functions, reproductive function is gradually declining, ovarian function in decline, some have entered menopause. In the ancient Chinese medical text “Suwen. Ancient Heavenly Truth” on women’s growth, development, reproduction, aging made a detailed description; women seven years old, kidney gas, teeth more hair. At the age of seven, the kidneys are full of energy, the teeth are longer, and the hair is longer. At the age of seven, the kidneys are full of energy, the teeth are longer, and the hair is longer. Three seven kidney qi average, so the real teeth born and long pole. The tendons and bones of the fourth seven years are firm, the hair is long and strong, and the body is full of strength. In the seventh year of the fifth year, the Yang Ming pulse declines, the face begins to burn, and the hair begins to fall. In the sixth and seventh years, the three Yang veins are weakened, the face is scorched, and the hair begins to turn white. In the seventh year, the Ren pulse is weak, the Taichong pulse is weak, the Heavenly Decadence is exhausted, and the Earth’s path is impassable; therefore, the form is bad and there are no children.
